Abstract The present invention relates to an intake structure of air filter for motor-driven two-wheeled vehicle. It can farthest avoid an air cleaner from sucking dust deposited on a power unit by a simple-shaped intake duct. The characteristic is that: An intake duct 93 is constituted of a small-diameter pipe 94 for communicating the upper end with the inside of a cleaner case 84, and a large-diameter pipe 95 having the diameter larger than that of the small- diameter pipe 94 and having its upper end communicated with the lower end of the smaller-diameter pipe 94. The distance L1 between the rear part releasing end of the large-diameter pipe 95 and the lower part opening end of the small- diameter pipe 94 is set shorter than the distance L2 between a part except for the rear part in the lower part releasing end of the large-diameter pipe 95 and the lower part opening end of the small-diameter pipe 94.
